AUXILIARY GENERATOR FOR OlL-GAS'LAMPS.

SPECIFICATION forming part of Letters Patent No. 642,974, dated February 6, 1900.

Application filed January 28, 1899. Serial No. 703,699. (No model.)

To aZZ whom it may concern:

Be it known that I, ALEXIS F. GILLET, of Kearney, in the county of Buffalo and State of Nebraska, have invented a new and Improved Auxiliary Generator for Oil-Gas Lamps, of which the following is a full, clear, and exact description.

My invention relates to an improvement for use with oil-gas lamps designed to facilitate the starting of the same into operation. My invention comprises an auxiliary generator designed for temporary use in connection with such lamps and to furnish a supply of gas which will last until the ordinary or service generator has become heated to such a point as to volatilize the oil.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is an elevation and partial section showing my device applied to a lamp; and

- Fig. 2 is an elevation of the same, taken at right angles to Fig. 1.

In using oil-gas lamps which have a generator heated by the burner it is necessary ordinarily to furnish some special means for heating the generator to such a temperature that it will volatilize the oil. Until the generator has been heated to this point the oil flowing through the same will not be volatilized and if burned will create smoke. In consequence it is the usual practice to provide some form of torch for heating this generator when the lamp is first lighted. This may be secured permanently to the apparatus or be a portable torch.

The object of my device is to furnish a carbureter operated by the attendant which will furnish a supply of carbureted air or gas sufficient to heat the generator to its working temperature. This device may-be applied to any lamp of the form which uses a generator heated by the flame of the lamp.

The lamp herein shown consists of a reservoir A, within which the oil is placed; a tube B and B, leading to the lamp; a generator D, which consists of a tube placed over the flame of the lamp; a mixing-tube E, and a lamp or burner L. These parts may be of any ordinary or useful construction with the single exception of the reservoir A. The valve 0 is placed between the tube B and the generator D for controlling the supply of oil. The reservoir Ais a closed reservoir-that is, may be closed, so as to retain a pressure of air therein. This reservoir, as herein shown, is provided with a filling-opening (1, located below the upper end of the reservoir, so as to form a small dome or air-space A above the filling opening. The lamp is carried by means of a rod 1, which is secured to the pipe B and extends upwardly alongside of the reservoir, terminating in a hook or other convenient means by which it may be suspended. Surrounding this rod or in any other convenient position is placed an air-reservoir F, which is connected bymeans of a pipe G with the interior of the oil-reservoir A. The pipe G extends downward within the oil, terminating near the bottom of the reservoir. A small pipe H is connected with the upper end of the reservoir or the air-space above the oil and extends downward alongside the pipes B, B, and E to the burner. At the burner its opening is controlled by a valve J.

A connection is provided at any convenient point upon air-resorvoir F, whereby it may be connected with any convenient means for compressing air. In Fig. 2 such a connection is shown at k, by which an air-pump K may be connected so as to fill the reservoir with compressed air.

The operation of my device is as follows: .lVhen it is desired to light a lamp of the character described, the reservoir F is filled with compressed air. When the valve J is opened, the air will escape from the reservoir through the pipe G, where it will bubble up through the oil in the oil-reservoir, thereby becoming charged with gas, so as.to be inflammable. The gas is then conducted through the pipe H to the valve J, and this valve being opened the gas will rise through the burner and may be ignited. It will be necessary for the burner to be supplied with gas from this means only for a short time, as the generator D will become quickly heated to such a temperature that it will volatilize the oil. The valve 0, which controls the supply of oil to the servicegenerator D, may be opened as soon as the burner has been lighted. It is thus possible to light a lamp of this character and have it burn from the first with gas without having to wait until the service-generator D has become sufficiently heated. W'ithout some device of this character it is an exceedingly slow process to light these lamps, as each lamp must be working in proper condition before the operator can leave it safely. This device will therefore save a great deal of time, and will also prevent smoking up of the mantles by having the oil burned beneath them. It will also save a great deal of trouble which arises from these lamps When not supplied with such a device, due to the explosive ignition of gas in the mixing-tube and chimney at the time of lighting. hen this happens, mantles and chimneys are apt to be destroyed.

It is not intended that the auxiliary generator described shall be of sufficient capacity to operate any great length of time. It is only necessary that it should be able to supply gas to the burner for a very short time.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An oil-gas lamp, having an elevated closed oil tank or reservoir, a gravity oil-feed pipe leading therefrom to the generator,means for supplying carbureted air to the burner Without exerting a displacing pressure upon the oil in its reservoir, said means comprising a separate compressed-air reservoir, a pipe leading therefrom to and discharging Within the oil-tank near its bottom, and a pipe leading from the top of the oil-tank and communicating With the burner, substantially as described.

2. An oil-gas lamp, having a generatorheated by the flame of the lamp, a combined oilreservoir and carbureter elevated to supply the oil to the generator by gravity, an oilsupply pipe leading from the bottom of said reservoir to the generator and containing a valve, a burner, a mixing-tube connected therewith by one end and having the other open end receiving the discharge from the generator, an independent reservoiradapted to be charged With air under pressure, a discharge-pipe leading therefrom and dischargin g beneath the oilin'the oil-reservoir, an auxiliary pipe leading from the top or air-space of the oil-reservoir to the burner, and a valve controlling the burner end of said auxiliary pipe, substantially as described.
